Kerman Center for Theoretical Physics, Laboratory for Nuclear Science and Department of PhysicsMassachusetts Institute of Technology-Cambridge, Massachusetts 02139,USA July 29, 1999 Microscopic Combinatorial approach is used to calculate the state and level densities with fixed exciton numbers, in some actinide nuclei. Deformed Saxon-Woods shell model was used as a basis from which all posible configurations were generated. The pairing interaction was taken into account by applying the BCS theory to each configurations. Both the spin and parity distributions were obtained,considering the deformation of the nucleus. Relevance of the result to parity nonconservation studies involving epithermal neutrons on 238U and 232Th is discussed. PACS: 21.60w

متن کاملSTUDY OF NUCLEAR LEVEL DENSITY AND SPIN CUT-OFF FACTORS
Nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹A‹63,from a microscopic theory, which includes nuclear pairing interaction. Single particle levels for both Seeger and Nilsson potentials were used in the calcdations. Level densities extracted from the theory are compared with their conesponding experimental values, It is found that the overall...
متن کاملCranked Relativistic Hartree-Bogoliubov Theory: probing the gateway to superheavy nuclei
The cranked relativistic Hartree+Bogoliubov theory has been applied for a systematic study of the nuclei around 254No, the heaviest elements for which detailed spectroscopic data are available. The deformation, rotational response, pairing correlations, quasi-particle and other properties of these nuclei have been studied with different parametrizations for the effective mean-field Lagrangian. ...
متن کاملKUNS 1385 Onset of Rotational Damping in Superdeformed Nuclei
We discuss damping of the collective rotational motion in A ∼ 150 superdeformed nuclei by means of a shell model combining the cranked Nilsson mean-filed and the surface-delta two-body residual force. It is shown that, because of the shell structure associated with the superdeformed mean-field, onset energy of the rotational damping becomes Ex ∼ 2− 3 MeV above yrast line, which is much higher t...
